Totarol Average Antibacterial Anti-Blemish Anti-Ageing Totarol at a glance Diterpene found in certain types of trees Has antioxidant + anti-inflammatory benefits Also antimicrobial Can cause skin irritation Totarol description Totarol is a diterpene, a type of compound found in plants, animals and fungi that serves as a base for bioactive compounds like phytol and retinol. Totarol is found naturally in _Podocarpus totara_, a tree native to New Zealand, as well as some types of juniper and eucalyptus. Totarol is an interesting ingredient, because in addition to its antioxidant properties (being plant-derived) and having some anti-inflammatory benefit, it also exerts antimicrobial protection. This has led to its inclusion in some products’ preservative systems (to prevent mold and bacterial growth). Research also shows the antimicrobial activity of totarol has an impact on _P. acnes_ bacteria, the primary bacteria whose overpopulation within skin is responsible for acne breakouts. The drawback, however, is that there are studies indicating totarol can cause skin irritation, which over time can make acne worse. The recommended use level of totarol in skin care is 0.1%, but some manufacturers claim up to 10% is suitable depending on formulary needs. It’s best to consider a product containing totarol for short-term use, however, it is also worth switching to an ingredient such as benzoyl peroxide, which has the same function and decades of research behind it proving its efficacy. Azelaic acid is another alternative to help alleviate blemishes and the marks they tend to leave behind.
